500+ Head-Fier
The T8iE is V-shaped and the EX1000 is bright neutral, both are dynamic systems and the T8iE excels as a general all-rounder while the EX1000 is less for general use and more for critical listening and monitoring.
As to whether or not one should own both, that's up to you.
Can you give some hints for Oriolus MK2 vs AK T8iE?
I saw the T8iE being better rated in your list, although I've read about Oriolus having a more tight, accurate and satisfying bass then T8iE, overall being a better IEM.
Is there anything specific which differentiate them?
I'm looking for a warm sound with deep, clean, impactfull bass, rich and full midrange, emotional and dense vocals, relaxed treble but with very good extension.
Thanks!
